Whakarāpopototanga: he pūhaumāota i whakakorikoria e te acetone, ā, i hangaia mā te whakatiotanga whakarewa i te 1,1,3-trichloroacetone me te parakore teitei o te 99.0%, me te hua o te 45% o Ngā Kupu Matua: 1,1,3-trichloroacetone; te hanga; te parakore teitei

Kupumatua

He mea nui te 1,1,3■trichloroacetone hei takawaenga mō te hanga waikawa folic. I tēnei wā, he roa te huringa hanga (48 hāora) te 1,1,3.acetone trichloropacetone, he iti te hua, tata ki te 17% noa iho te ihirangi o te 1,1,3-trichloropacetone, i muri i te tango wai, ko te ihirangi he 51.9% noa iho. Ā, he nui te utu hanga, he iti te whakatikatika hua. Ko ēnei katoa ka arahi ki ngā utu hanga waikawa folic ā-rohe nui, he uaua ki te whakapai ake i te ihirangi me ētahi atu raruraru. He maha ngā tuhinga ā-rohe me ā-iwi i pānuihia e te kaituhi. Whai muri i ngā whakamātautau me ngā rangahau maha, i tāpirihia e mātou he whakakorikori me te whakahaere i te tere o te haukini, ka whakaiti i te wā tauhohenga ki te 1,1,3-3 trichloropacetone i roto i ngā hāora 24, me te tioata 1,1,3-3 trichloropacetone me te parakore neke atu i te 99% me te hua neke atu i te 45%.

1. Ngā taahiraa whakamātautau

I roto i tētahi pounamu kaki-whā me tētahi whakapūmau porowhita 500ml, i whakaohokia tētahi nui o te acetone me te whakakorikori, ā, i whāngaihia ki te chlorine i te pāmahana tauhohenga o te 10~30 W. Tīmatahia te wā, kati te tuku i roto i te chlorine i ētahi haora i muri i te tauhohenga, ā, me whakaoho tonu mō te 1 haora. I tāpirihia he rauemi motuhake pērā i te whakarewa ki te ranunga hua, i whakaohokia mō te 1 haora i a ia e whakamatao ana ki te 10°C tioata, ka tangohia te 1,1,3-trichloroacetone.

1. 1,1,3. Te whakatau whiriwhiri i te parakore o te trichloroacetone

I whakamahia te chromatograph hau Varin 3700, te pou whakakī QF・1 me te pūoko FID hei whakatau i te hua parakore o te hua me te otinga pūhaumāota.

He awe nui, kei te Ripanga 1 he huinga hua whakamātautau. Mai i te Ripanga 1, kua tino piki ake te whiriwhiringa iti rawa o te 1,1,3-trichloroacetone (tata ki te 19.1%) me te kore he whakakorikori, ā,

Kei te Ripanga 2 te rārangi o ngā raraunga whakamātautau.

I kitea i roto i te whakamātautau he wawe te fluchlorine (12 hāora) ā, he muri iho (8 24 hāora), ko te nuinga o te chlorine ka puta, he puhoi te tauhohenga, ā, he tere te reo (28 hāora). Ina mutu te hau chlorine, ka tino heke te whiriwhiringa hua me te hua. I whakaatuhia e ngā hua he puhoi ake te whakaputanga o te 1,1,3 i te

E whakapono ana te kaituhi ko te tukanga tauhohenga o te whakaputanga acetone chloride ko:

Ka whakahaerehia te tauhohenga me te V1 1 2-5 hei tukanga matua.

E ai ki ngā raraunga o te Ripanga 2, ko te raupapa tere tauhohenga o ia taahiraa ko

I runga i te tere o te tauhohenga o ia taahiraa,

Ka kitea mai i ngā raraunga o te Ripanga 3, nā te iti o te rerekētanga o te pūwāhi kohua i waenga i te 1,1,3.trichloroacetone me ngā hua taha, he uaua te wehewehe i te tango wai, ā, he māmā noa te wehewehe. Ahakoa ka taea te tango i te nuinga o ngā hua I, he uaua te parakore.

ka whakahaerehia e mātou te tere o te whakawhiti hauota i ia wāhanga,

hei whakatutuki i te whāinga o te whakaiti i te wā whakawhiti chlorine me te aukati i te whiriwhiringa o te whakanui ake i te tere tauhohenga tuarua mā te 1,1,3 trichloroacetone.

Ka tangohia, ka whakatikatikaina rānei te wai acetone chloride ki te wai hei whakanui ake i te ihirangi o te 1,1,3-trichloroacetone, ā, i whakamahia e te kaituhi te 1,1,3-trichloroacetone hei whakatioata mai i ētahi atu hua taha.

Kei roto i te Ripanga 3 te whakarārangi i te parakore o te hua i whiwhihia mā roto i ngā tikanga wehewehe.
